A low power high efficienecy DC-DC converter

Switching converters are widely used in power management because of their low power consumption and variable output voltage. However, with the development of technology, the conversion efficiency of converters is improved. using dynamic bias technology and dead-time control technology, reducing the conduction loss and overlapping loss of power transistors in switching converters, reducing the overall power consumption and improving the overall conversion efficiency. A buck DC-DC converter based on voltage mode is simulated and verified.The optimal input current is 3.6V and the load current is 200mA. The conversion efficiency is 91.67%. The performance index is enhanced.
